Need monitoring? The Solis WIFI adaptor is compatible with all Solis inverters, click here for details.

For export limitation and consumption monitoring =< 10m of inverter to incoming power supply then please use part (SOL-CT-100A-10M – please note: A firmware upgrade is required to the latest version for this to function). For any distances longer then this please purchase the Solis EPM (SOL-EPM1-5G)

G99DNO approval

This is the first S6 dual tracker over the G98 line. Pick it when the roof can carry around 6 kW of panels and you are willing to apply to the DNO first.

Getting it connected

G99 application before installation

Rated output is 17.4 A at 230 V, over the 16 A single-phase G98 limit. The DNO has to approve it first. If they cap export, the built-in export manager can hold it to that figure. The G100 certificate issued for SOL-4.0-S6-DT-DC is in the Documents tab for that case.

String layout

There are two MPPTs, one string on each, at 14 A with 22 A short-circuit. Tracking runs from 90 V to 520 V, with generation from 120 V and 600 V as the input limit. Twelve 500 W panels, six per face, give the full 6 kW.

Supplied / not supplied

  • DC switch integrated into the inverter
  • Export limitation built in, with DRM
  • DC arc-fault protection (AFCI), activated at commissioning
  • CT clamp for the export limit, sold separately
  • Wi-Fi or GPRS monitoring stick

FAQ

Could I fit it under G98 by limiting export?

An export-limited install still goes through the DNO. It becomes a G99 application with a G100 export-limiting scheme, and the certificate for that is provided.

What is its maximum AC current?

21.0 A. Size the circuit protection from that figure.

How does it compare with the 3.6 kW?

It uses the same input stage and case (11.2 kg), with more output: 4.4 kVA against 4 kVA.

Are the packs the same inverter?

Yes, the S6-GR1P4K throughout, as a single, a pack of 5 or 10, or a pallet of 16. Compare per-unit prices below.
